摘要
针对SR电动机存在的振动和噪声问题,分别应用实验模态分析法和计算模态分析法研究了SR电动机的动力特性,得到了SR电动机定子的固有频率和主振型,计算值与实验测量值吻合较好,所得数据可为制定抑制SR电动机的振动和噪声方案提供参考.
In order to effectively reduce the vibration and noise of the Switched Reluctance (SR)motor,it is essential to determine the original frequency of SR motor accurately.In this paper we made some researches on the vibration characteristic of it in two methods: Modal testing analysis and Modal calculating analysis, and gained the correct original frequency and oscillation deformation of SR motor. Analytical results are compared with experimental results, and a perfect agreement is obtained. The conclusion can provide valuable reference to cancel the vibration and noise for SR motor.
